GARBURETER-ADJ'USTER.

Specification of Letters Patent.

Patented Apr. 1, 11919.

Application filed August 22, 1917. Serial No. 187,626.

T 0 all whom it may concern.

Be it known that I, WILLIAM BARBOUR, av citizen of the l nited States. and a resident of, Everett, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Carbureternkdjusters, of which the following is a full. clear, and exact specification.

In certain makes of automobiles, it is an exceedingly awkward thing to adjust the carbureter. and especially on those cars whose dash has had a speedometer board applied thereto. On these cars, the chauffeur mustfrequently stop before it is safe for him to lean over downward and to one side in order to reach and actuate the adjusting rod provided for the purpose.

The purposes of my invention are, first,

to provide an adjusting means which thechaufi'eur can manipulate without danger or inconvenience, and, second, to su )ply means whereby he can see at a glance the point of adjustment at which the device is set.

In the drawings forming part of this specification, Figure l is a plan view of portions of an automobile showing my improvements appliedthereto. Fig. 2 is a side sectional elevation on the line XX in Fig. 1. Fig. 3 is a sectional detail view of the adjusting fork and allied parts.

The reference numeral 1 designates the dash of an automobile; 2. the carbureter; and 3, the forked rod for the adjustmentof the carbureter valve. Previous to my invention, the rod 3 was prolonged through the dash 2 and formed with a short arm by means of which it was turned. Instead of this, I dispense with such arm, and substitute a spur gear or pinion 5 in lieu thereof. An entirely new rod may be used, or if preferred and as would be the case in applying my improvement to a used car. I cut off the I upper three or four inches of the rod 3, and splice upon the severed end a suitable length of new rod 3 bearing the pinion 5, a splicing sleeve 8 having set screws 8 being provided for the purpose.

A block 4 suitably attached to the dash 1 forms the upper bearing for the rod 3 or its prolongation 3. and also a support for a rack G which meshes with the pinion 5. At the opposite side of the car. is a similar. spur gear or pinion 7 meshing with a rack 9. this rack being joined in any suitable manner to the rack 6, as by a twisted bar 10, to cause them to reciprocate as one.

The rack 9 is slidably supported by a block 11 attached to the dash 1, and the pinion 7 is mounted on the end of a spindle 12 rotatable in the block 11. The other end of the spindle turns in suitable bearings, preferably in the plate 16 which is fastened to the visible surface of the speedometer board 13, and the extremity of the spindle has rigidly mounted thereon an indicator It provided with an actuating wing 15. The plate 16 being given suitable indicator markings, the rotation of the indicator 14 and of the connected carbureter valve is made visibly correlated.

A helical spring 17 pressing between the inner surface of the dial plate 16 and a suitable stop on the spindle 12, creates sufficient friction to keep the spindle and connected parts from undesired motion.

The rod 3 being of well known form, has forks 20 at its lover end designed to loosely enter holes 22 in the valve operating disk 21. I prefer to place in each hole 22 a small thimbl'e 23 kept from dropping down and out therefrom by means of a shoulder 24, the forks 20 being slidable in these thimbles. These thimbles enable lost motion to be taken up andthereby insure that every slight turn of the indicator Will correspondingly affect the carburetor valve, and so render the device preferably responsive.

lVith the type of car for which my improvement is specifically designed, the steering shaft is also directly below the indicator 16. Hence, all the chaufieur needs to do in adjusting this carburetor is to drop his eye for a moment to the dial and with his free right hand move the indicator to the degree desired. This he can do Without changing his position. or to the slightest extent losing his control of the car.

What I claim isi 1. The combination with anautomobile or the like having a carbureter, of an operative shaft rising from the latter. a pinion on the upper'end of said shaft, a pinion having a spindle for its support, an indicator carried by said spindle. and an elongated connection between said pinions including rack teeth meshing with each pinion.

2. The combination with an automobile or the like having a carbureter. of an operative shaft rising from the latter, a pinion on the upper end of said shat't, a rack meshing therewith, a second rack substantially parallel withbut separated from the first rack, connection'betwecn said racks, a pinion'meshing with the second-named rack. a spindle carrying the last-named pinion, an indicator carried by said spindle, and a dial for said indicator.

3. The combination with an automobile or p the like having a carbureter, of an operative rod rising from the latter, a dash, a speedometer board spaced from the dash, a dial plate attached to the speedometer board at the side of the car farthest from the carbureter, a spindle passing through said dial plate, an indicator fixed on the end of said ion and slidably supported by said block, a

block-rotatably receiving said rod, a pinion mounted on said rod, a rack slidably supported by said block and meshing with said pinion, and a twisted bar uniting said racks, whereby a turn of said indicator adjusts the carbureter.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 20th day of August, 1917.

WILLIAM BARBOUR.
